And btw, PCI connectors are soldered directly on the motherboard, there are no such things as PCI-cables. Although, you will require extra power cables for the 8800GTX. All of that is covered in my guide.
And remember that you will not benefit from putting 2 graphic cards in the Mac Pro, as you can only run 1 card in normal speed (16x) or 2 cards at half speed (8x).
i mean the pci-e power cables. there are 2 plugs on the motherboard to connect them to but they are not a standard connector. I want the proper apple cables, i dont want to make them.
